| Antigen Distribution | CD4 (T4, Leu3a) is a 55 kDa single-chain transmebrane glycoprotein expressed on a subset of T lymphocytes (''helper'' T-cells) and also on monocytes, tissue macrophages and granulocytes. In extracellular region there are 4 immunoglobulin-like domains (1 Ig-like V-type and 3 Ig-like C2-type). Transmembrane region forms 25 aa, cytoplasmic tail consists of 38 aa. Domains 1, 2 and 4 are stabilized by disulfide bonds. The intracellular domain of CD4 is associated with p56Lck, a Src-like protein tyrosine kinase. |
| Usage | The reagent may have application in various test methodologies, including Flow Cytometry. Vial has sufficient volume for 100 tests, if used at 10 μL·/·test. User has responsibility for determining reagent quantity per test for any ASR reagent. |
| Storage Buffer | The reagent is provided in stabilizing phosphate buffered saline (PBS) solution, pH ≈7.4, containing 0.09% (w/v) sodium azide. |
| Storage | Avoid prolonged exposure to light. Store in the dark at 2-8°C. Do not freeze. |
| Stability | Do not use after expiration date stamped on vial label. |
